Writing in the Mathematics Classroom -- Explanation and Evaluation

Pupils engage in an activity where one partner reads directions while the other follows those directions to complete a math task (such as bisecting an angle). As a reflection, they examine products to see what information the best...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is taken to discuss...

To add or subtract ... how do you make the decision? The video instructor explains the process of writing a numerical expression from a verbal expression. While writing the expressions, he provides explanations for his decisions.

Products, quotients, sums, and differences are the operations to know. A thorough lesson presentation explains how to analyze a verbal expression to create a mathematical expression. Explanations of terminology and order help learners...

Introduce exponents to your learners with this quick video about writing numerical expressions. It explains the foundation of exponents and demonstrates a few examples. Use with other four videos in the series for examples on evaluating...

Show your learners that exponents are important in the order of operations. The video presents a useful method for evaluating an algebraic expression with exponents and attempts to eliminate the common mistake of multiplying the exponent...

The use of manipulatives creates a playful atmosphere in your classroom. Using precreated disks, pupils translate verbal expressions into mathematical equations, offering a great way to practice the new vocabulary in a nonthreatening...

See how geometry and exponents relate and show your learners how to find area and volume. The video shares the idea of why we use exponents with area and volume and does an example of each. Examples do not evaluate exponents, but that...

Evaluate exponents to decide which method pays more money. Use what your learners know about order of operations to practice solving a word problem to determine which payment is higher. The final video in the series of five, reviews...

How do algebra learners know the value of an algebraic expression that contains a variable? This video shows your number crunchers how to evaluate an algebraic expression by substituting a given number for the variable. In fact, it...
